This paper studies the role of taxation in durable good markets with dynamic monopolies. By conditioning the marginal tax rate on the volume of trade, the regulator can provide incentives for the monopolist to accelerate trade. When marginal cost pricing generates a loss for the monopolist, strategic delay cannot be avoided under regulatory budget constraint and the effects of tax policy depend on the monopolist's ability to commit. In the context of binary consumer types, we find a tax policy involving “back-loaded subsidy” that achieves the second-best outcome with commitment. In contrast, without commitment, a “front-loaded subsidy” improves welfare.

We study how the inaccuracy of a costly certification technology affects a monopolistic seller's profitability. We compare three scenarios: no certification, a 100% accurate certification, and a 50% accurate certification that produces accurate evaluations half the time. The noisy certification environment is never the most profitable and, depending on the buyers' loss aversion, can be the least profitable. However, a noisy certification can be more profitable than an accurate one, as it discourages the over-certification that occurs in an accurate certification environment. Experimentally, the noisy certification is shown to be the least profitable treatment, whereas the accurate certification is shown to be the most profitable.

In current power markets, the bulk of electricity is sold wholesale and transported to consumers via long-distance transmission lines. Recently, decentralized local energy markets have evolved, often as isolated networks based on solar generation. We analyze strategic pricing, investment, and welfare in local energy markets. We show that local energy markets yield competitive equilibrium prices and provide efficient investment incentives. Yet, we find that strategic behavior leads to allocative inefficiency. We propose a clearing mechanism that induces truth-telling behavior and restores first-best welfare.

This article seeks to quantify the importance of price information in reducing consumer search costs and equilibrium price dispersion in a competitive setting. It exploits a natural experiment in the retail gasoline industry in which stations post the prices of only certain grades of gasoline on large street-side signboards, and not others, except where required by law. Differential-by-grade signboard information predicts a specific curvature in price dispersion across grades, and differentiates itself from other noninformational factors such as income and cost. The impact of readily-available price information on search and price dispersion is found to be exceptionally large.

We model firms' quality disclosure and pricing in the presence of cursed consumers, who fail to be sufficiently skeptical about undisclosed quality. We show that cursed consumers are exploited in duopoly if firms are vertically differentiated, if there are few cursed consumers, and if average product quality is high. Three common consumer protection policies that work under monopoly, that is, mandatory disclosure, third party disclosure and consumer education, may all increase exploitation and decrease welfare. Even where these policies improve welfare, they often lead to a reduction in consumer surplus. Our conclusions hold in extensions with endogenous quality and horizontal differentiation.

Bid delegation to specialized intermediaries is common in internet ad auctions. When the same intermediary bids for competing advertisers, its incentive to coordinate client bids might alter the functioning of the auctions. This study develops a methodology to detect bid coordination and presents a strategy to estimate a bound on the search engine revenue losses imposed by bid coordination. When the method is applied to data from auctions held on a major search engine, coordination is detected in 55% of the cases of delegated bidding and the search engine's revenue loss ranges between 5.3% and 10.4%.

This article develops and estimates an industry equilibrium model of the Korean electric motor industry from 1991 to 1996. Plant-level decisions on R&D, physical capital investment, entry, and exit are integrated in a dynamic setting with knowledge spillovers. We apply the novel approximation of oblivious equilibrium to estimate the R&D cost, magnitude of knowledge spillovers, adjustment costs of physical investment, and plant scrap value distribution. Knowledge spillovers are essential to explaining the firm-level productivity evolution and the equilibrium market configuration. A $��15�\%�$ R&D subsidy maximizes industry output and is broadly consistent with a past policy initiative of the Korean government.

Platforms use price parity clauses to prevent sellers setting lower prices when selling through other channels. They claim these restraints are needed so platforms have incentives to invest in providing search services—without them, consumers would search on the platform but then switch to buy in a cheaper channel. In a model incorporating these effects, we find that wide price parity clauses lead to excessive platform investment while narrow (or no) price parity clauses lead to insufficient platform investment. Taking these investment effects into account, wide price parity clauses lower consumer surplus but have ambiguous effects on total welfare.

Using information on price bids in wholesale electricity pools and empirical techniques described in the literature on electricity markets, this study identifies the market power mitigation effect of public firms in the Colombian market. The results suggest that while private firms exercise less market power than is predicted by a profit-maximization model, there are marked differences between private and public firms in their exercise of unilateral market power. These findings support the hypothesis of the market power mitigation effect of public firms.

We analyze oligopolistic third-degree price discrimination relative to uniform pricing when markets are covered. Pricing equilibria are critically determined by supply-side features such as the number of firms and their marginal cost differences. It follows that each firm's Lerner index under uniform pricing is equal to the weighted harmonic mean of the firm's relative margins under discriminatory pricing. Uniform pricing then lowers average prices and raises consumer surplus. We can calculate the gain in consumer surplus and loss in firms' profits from uniform pricing based only on the market data of the discriminatory equilibrium (i.e., prices and quantities).
